Image capturing optical lens assembly

An image capturing optical lens assembly comprising six lens elements, the six lens elements being, in order from an object side to an image side:

• a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element;
• wherein each of the first lens element, the second lens element, the third lens element, the fourth lens element, the fifth lens element and the sixth lens element has an object-side surface facing the object side and an image-side surface facing the image side;
• wherein there is an air gap between optical effective regions of every adjacent lens elements of the six lens elements;
• wherein the second lens element has the image-side surface being convex in a paraxial region thereof;
• the third lens element with negative refractive power has the image-side surface being concave in a paraxial region thereof;
• the fifth lens element with positive refractive power has the image-side surface being convex in a paraxial region thereof;
• the sixth lens element with negative refractive power has the object-side surface being convex in a paraxial region thereof and the image-side surface being concave in a paraxial region thereof, and the image-side surface of the sixth lens element comprises at least one inflection point;
• wherein an absolute value of a curvature radius of the object-side surface of the third lens element is greater than an absolute value of a curvature radius of the image-side surface of the third lens element, and an absolute value of a curvature radius of the object-side surface of the fifth lens element is greater than an absolute value of a curvature radius of the image-side surface of the fifth lens element;
• wherein a curvature of the object-side surface of the third lens element is C5, a curvature of the image-side surface of the third lens element is C6, and the following relationship is satisfied:
• −0.4<(C5−C6)/(C5+C6)<0.
